2.6 Missing values
2.7 Checking Scale quality
2.7.1 Correlation of comorbidity
If one suffers from one comorbidity, does he/she suffer (in general) from other comorbidities too? NZV variables are excluded.
We should do this more stringently, but let’s start with a brief look to the items of ChOCI, to see whether they are correlated (as they should be, at least for common subscale-items). Those are quite a few. 
2.7.2 Cronbachs Alpha and interitem correlation
Some item were negatively correlated with the scale (ChOCI_R_C_26_PRE-). They should be checked.

3.1 Associations with treatment response
3.1.1 Comorbidity as predictors
The (non-nzv) comorbities are: Depression, PanicDisorder, SocialPhob, SpecificPhob, TourettesTics, ADHD, GAD. The Odds ratios of the comorbities with the outcome variable are: 0.68, 0.43, 1.05, 0.23, 2.2, 3.93, 0.67.
The relative risks of the comorbities with the outcome variable are: 0.84, 0.66, 1.02, 0.45, 1.3, 1.49, 0.83.
Let’s plot the assocation of the comorbitity with the outcome var responder_3m. To that end, let’s tabulate the the 2x2 matrices (contingency matrices) for each comorbidity (yes/no) vs. responder (yes/no). For convenience, proportions (%) are depicted.
## [1] "Depression"
##
## 0 1
## 0 0.55 0.38
## 1 0.04 0.04

## [1] "responder_3m"
##
## 0 1
## 0 0.59 0.00
## 1 0.00 0.41
Wait a minute, it looks as if there a few persons where responder_3m == 1! Does that mean, most participants did not respond (ie., no success)?
Hm, let’s divide that up for each comorbidity, and plot it:
Hoaza! That looks strange! Can that be? Surely there must be some bug, either in my code, what may well be the case (Deus adiuvet me), or in the data.
Let’s look at it from some other perspective, different code, and plot it again, and see what happens:
And what it about if we eyeball the plain number:
| key | responder_3m | n |
|---|---|---|
| ADHD | 0 | 33 |
| ADHD | 1 | 23 |
| ADHD | NA | 5 |
| Agoraphobia | 0 | 33 |
| Agoraphobia | 1 | 23 |
| Agoraphobia | NA | 5 |
| Depression | 0 | 33 |
| Depression | 1 | 23 |
| Depression | NA | 5 |
| Dystymia | 0 | 33 |
| Dystymia | 1 | 23 |
| Dystymia | NA | 5 |
| EatingDis | 0 | 33 |
| EatingDis | 1 | 23 |
| EatingDis | NA | 5 |
| GAD | 0 | 33 |
| GAD | 1 | 23 |
| GAD | NA | 5 |
| ODD | 0 | 33 |
| ODD | 1 | 23 |
| ODD | NA | 5 |
| PanicDisorder | 0 | 33 |
| PanicDisorder | 1 | 23 |
| PanicDisorder | NA | 5 |
| PTSD | 0 | 33 |
| PTSD | 1 | 23 |
| PTSD | NA | 5 |
| SeparationAnx | 0 | 33 |

| SeparationAnx | NA | 5 |
| SocialPhob | 0 | 33 |
| SocialPhob | 1 | 23 |
| SocialPhob | NA | 5 |
| SpecificPhob | 0 | 33 |
| SpecificPhob | 1 | 23 |
| SpecificPhob | NA | 5 |
| TourettesTics | 0 | 33 |
| TourettesTics | 1 | 23 |
| TourettesTics | NA | 5 |
Hm, the same picture emerges: With comorbidity always 23 cases, without comorbidity also 33 cases. Somewhere there must be a bug…
4 Most important variables (narrow data set)
4.1 Type of most important variables
Let’s focus on the most important variables, to make life easier.
That should be all sum scores. Let’s look for them:
Ok, the variables are CYBOCS_pre_sum, ChOCI_R_C_sumsym_PRE, ChOCI_R_C_sumimp_PRE, EWSASC_sum_PRE, SCAS_S_C_sum_PRE, CDI_S_sum_PRE, ChOCI_R_P_sumsym_PRE, ChOCI_R_P_sumimp_PRE, FAS_PR_sum_PRE, EWSASP_sum_PRE, SCAS_S_P_sum_PRE. In total, 11 variables.
We can probably safely ignore ID. We should include basic and demographic variables:
Which gives us group, sex, age, Birthcountry, Education_parent, OCDonset, yearswithOCD, contact, distance, medication, medication_yesno, treatm_exp, OCD_treatm_exp, responder_3m, CYBOCS_3m, another 15 variables.
Of particular interest are of course responder_3m, CYBOCS_3m (outcomes) and group (experimental factor).
Next, let’s name the comorbidities.
These are Depression, Dystymia, PanicDisorder, Agoraphobia, SeparationAnx, SocialPhob, SpecificPhob, PTSD, TourettesTics, ADHD, ODD, EatingDis, GAD.
In total, 3 sets of variables then: basic variables (including outcome and experimental variables), sum scores of psychometric battery, and comorbidity.
In total, 39 Variables: group, sex, age, Birthcountry, Education_parent, OCDonset, yearswithOCD, contact, distance, medication, medication_yesno, treatm_exp, OCD_treatm_exp, responder_3m, CYBOCS_3m, CYBOCS_pre_sum, ChOCI_R_C_sumsym_PRE, ChOCI_R_C_sumimp_PRE, EWSASC_sum_PRE, SCAS_S_C_sum_PRE, CDI_S_sum_PRE, ChOCI_R_P_sumsym_PRE, ChOCI_R_P_sumimp_PRE, FAS_PR_sum_PRE, EWSASP_sum_PRE, SCAS_S_P_sum_PRE, Depression, Dystymia, PanicDisorder, Agoraphobia, SeparationAnx, SocialPhob, SpecificPhob, PTSD, TourettesTics, ADHD, ODD, EatingDis, GAD.
4.2 Coarse model
Vague defined, the model can be described as consisting of these predictors: demographics, psychometric scales, treatment (group), comorbities. The outcome is treatment response.
4.3 Missing values and sum scores
When tallying up sum scores, missing values cause problems. Assume 10 items to summed up. What if I have not responded to 9 items? If you count “zero” for the missing values, you will dramatically underestimate my true score. I wonder how the sum scores have been built here.
4.3.1 ChOCI scale (self-rated comorbidity)
The most items appear in the ChOCI scale. So let’s look there first.

Ok, good, no missings. Have they been replaced somehow? Where the participants forced to give some answer? This might be of interest for gauging the psychometric quality of the scale.

5 Interocular Trauma Test
5.1 Outcome: responder_3m
Before applying some sophisticated (aka esoteric) models, let’s perform the intraocular trauma test for the data: let’s see whether the effect is so crisp that it hits us right between the eyes. That is., is there an association between group and response?
Because for the fun of it (and because the question if of particular interest), let’s plot from different point of views.
Hm, it appears as if the experimental group was less successful than the control group. That result might hit us between the eyes… But one would certainly hope for something the other way round.
The bare numbers:
| group | responder_3m | n |
|---|---|---|
| ICBT | 0 | 21 |
| ICBT | 1 | 10 |
| ICBT | NA | 2 |
| waitlist | 0 | 12 |
| waitlist | 1 | 13 |
| waitlist | NA | 3 |
5.2 Outcome: CYBOCS_3m
For this outcome, it seems as if there was some (slight?) advantage for the treatment group. However, the overlap is substantial.
Here come the bare figures:
| group | group_mean | group_md | group_sd | group_IQR |
|---|---|---|---|---|
| ICBT | 14.22581 | 14 | 5.903161 | 7 |
| waitlist | 12.56000 | 12 | 6.807349 | 9 |
